This invention relates to a coil handling mechanism, 4and,^more particularly, to a device for effecting the transfer of 'bundles of coils from one type of conveyer to another.

In my co-pending application, Serial No. 41,807, flied September 23, 1935, now Patent No. 2,074,809, dated March 23, 1937, I have illustrated one form of coil handling device for| transferring coils from an endlessconveyer toa hook conlo veyer. The transfer of the `coils in'that application is effected by means of a double-ended hook depending from a carriage which rides on a track'- way extending between, and substantially above, the endless conveyer and the hook conveyer.

EI The endless conveyer is arranged to directl'coils of rod to a point above that at which the transfer'is effected, where, by force of gravity they are, caused to slide down an inclined apron to a point of repose in the verticaldsubstantially adjacent the double-ended hook, for easy engagement by the latter.

' It was found that in `handling the coils in, the above described manner, the sliding of 'the coils down the inclined apron from the initial conveyer to the point of repose, subjected each bundle lto such sudden and violent impact as to cause its convolutions to become disarranged, whereby great inconvenience in subsequent handling and processing of the coil was incurred.

'111e present invention has for an object, obviating the above dilculty by providing a means associated with the initial conveyer for handling the 'coils So-that their orderly arrangement will be-preserved,` y

g5 Other objects and advantageswill` become apparent hereinafter by reference to the annexed specification when considered `in conjunction with the accompanying drawings, in which:

Figure 1 is a top plan I view of the invenco ma l i Figure 2 is a side elevational view thereof.

Figure '7 is awiring diagram of the electrical 50 system involved in the operation of the doubleended hook transfer device. t

Since the construction and operation of the- 4.double-ended hook transfer device is substantially 'the same as that shown and described in 55 my co-pending application above referred to, a,

detailed description thereof will not be given here; the reference numerals in the drawings .greferring thereto being1 the same as those applied to the drawings and'used in the description of my co-pending application, to which reference 5 may be made for a complete understanding ofA the operation thereof. It will suffice to say that the device serves to transfer-the rod bundles 2,

reclining upon an endless conveyer comprising' an apron 3, intermittently moved dogs 4, and 10 -motivating conveyer chain 4a, to hook conveyer 5; the latter being driven past the vdischarge end of the horizontal conveyer to receive the coils therefrom. The coils on the horizontal conveyer are arranged for engagement by the doubleended hook i0 depending from carriage 8, which is adapted to ride on trackway 6. The trackway 6 is arranged to span the distance between the movement of the carriage 8 to the opposite end of the trackway 6, and by an accompanying rotary movement of the double-ended hook.

tion a rod bundle thereon.` The table I is piv- 40p oted to the horizontal 'conveyer by means of a shaft 42 in 'such manner that, rotary motion, when imparted to the shaft in the proper direc-fr tion, will cause the table to be raised to a sub-f stantially vertical position, as is shown in dotted 45 lines in Figure 2. It is preferable to coordinate the movement of the table I with that ofl any conveyer with which it is associated so that a coil is delivered thereon only Vwhen the table is in the horizontal. Any suitable conveyer control means (not shown) may be employed for this purpose, whereby, after a coil has been delivered upon the table I, or

Wheny the tableis in -its elevated position,'the horizontal conveyer will h e de-energized until the table is once more at rest in the horizontal. Thereafter the operation is repeated;

The raising and lowering of the table is also coordinated with whatever mechanism it is associated for removing coils therefrom, and, in the present instance, the double-endedhoolr/mechanism has been used for purposes of illustration.` However, it will be understood that the table of the present invention is equally applicable to* any other type of discharge mechanism or conveyer of the. same general type with which it associated. It will be seen that the carriage carrying the double-ended hook' is positioned at` the right hand side of trackway 6 when receiving a bundle of rods from the table I, as viewed in Figure'2, and that it is positioned on the left hand side of the trackway 6 when the. doubleended hook is in position to discharge coils upon the traveling hooks 5. This movement of the carriage has been taken as one means whereby the operation of the table I could be properly coordinated with the operation of these other conveyers with which it is associated.

To this end, a shaft 40 is transversely jourr naled at the right hand extremity of the track- Way 6, as viewed in Figure 2, above a' position slightly in front of the table I. This shaft is adjacent the line of Y., travel of the carriage. Rigidly affixed at each end of this shaftis a bell-crank 4I, both of which are aiforded simultaneous, intermittent actuation by the carriage 8 through the means of pitmans 45, which are pivoted at one of their ends to the carriage 8, and at their other ends are fastened to the bellcranks 4I by slip joints afforded by slots 46 extending longitudinally of the pitmans 45.

The shaft 42, by which the table I is pivoted, is provided at each of its ends with .a lever 43, both of which are connected to the bell-cranks '4I by means of connecting rods 44 on their respective sides.

The above arrangement is such that th'e bellcranks 4| remain stationary except when the carriage 8 approaches-a position above the table lI. When this occurs, the inner limits of the slots 46 are brought into engagement with-the bell-cranks 4I, wherebyV the pitmans 45 are caused, through the latter, and by means of connecting rods 44, to turn the levers 43 carried by shaft 42, and thus cause the table I to raise and perform its function of lifting a rod bundle to an upstanding position, so that one ofthe ends ofthe double-ended hook may enter the '-same. After the .double-ended hook has been operated to remove the bundle from the table in the same manner as is described in 'my copending application, above referred to, the carriage is actuated to lift and transport the hook, while simultaneously turning the same, to such a position where. the bundle may be discharged upon one of the moving hooks 5. This recessive action of the carriage `8 permits a retrogressive movement of the bell-cranks 4I, the connecting rods 44, the levers 43, and shaft 42, whereby the table I is returned to its horizontal position.

It is obvious that this operation is/'automatid and is responsive to the movement of the car-' riage 8 to positions toward and away from the tilting table. However, it will also be understood that thetable constituting the subject matter of the present-invention may be associ- A suitable way with the operation of such transfer mechanism.

It will be seen from the foregoing, that I have provided a novel means whereby the orderly arrangement of the coils is preserved throughout the manipulation required to transfer it from one conveyer to another, and it will be observed that the tilting table disclosed herein affords continuous, uniform, and adequate .support for the bundle at all times.
